  • Small business: what should I know about computer security?

    - by geschema
    I run a small (1 man) consulting company in the field of embedded systems, working from home using a standard DSL internet access. My main development machine is a Windows XP PC, which is connected to the router with an ethernet cable. I also have a MacBook Pro laptop, which is connects to the network via WLAN (WPA-PSK). Besides enabling the Windows firewall, not using IE, having an up-to-date antivirus program and strong passwords, what do I need to know to keep my customers' data safe on these computers?

  • Unable to access certain websites from a computer

    - by matt74tm
    One of the desktop computers in my office is unable to access some particular websites. We've tried from Chrome, IE, Firefox, but no luck. eg: http://spsims.wto.org/ -> click on "Regular notifications" On the affected computer, every browser times out after the click. Whereas it should redirect the user to http://spsims.wto.org/web/pages/search/notification/regular/Search.aspx How can I diagnose this further? This is a Windows XP machine.

  • CUPS in linux and printer

    - by yogesh
    How can I achieve the following behavior? CUPS Server communicate with hardware printer by using the "PostScript3" language and the LPD/LPR protocol to manage and transmit printing jobs. CUPS server must be configured to accept following file formats: PS, TXT, PDF, JPEG and PNG. This means only these files get printed and others should be blocked. I want to connect actual hardware printer using IPP from the linux machine.

  • Can't copy and paste to Netbeans when accessed over RDC

    - by Freiheit
    I use Netbeans for development and I access it by using a Windows Remote Desktop Connection back to my workstation at HQ. This is a great set up except for one thing, I cannot copy text on my local machine and paste it into Netbeans. I can copy and paste into other applications. Any ideas as to the cause? How can I fix it?

  • How to setup ssh's umask for all type of connections

    - by Unode
    I've been searching for a way to setup OpenSSH's umask to 0027 in a consistent way across all connection types. By connection types I'm referring to: sftp scp ssh hostname ssh hostname program The difference between 3. and 4. is that the former starts a shell which usually reads the /etc/profile information while the latter doesn't. In addition by reading this post I've became aware of the -u option that is present in newer versions of OpenSSH. However this doesn't work. I must also add that /etc/profile now includes umask 0027. Going point by point: sftp - Setting -u 0027 in sshd_config as mentioned here, is not enough. If I don't set this parameter, sftp uses by default umask 0022. This means that if I have the two files: -rwxrwxrwx 1 user user 0 2011-01-29 02:04 execute -rw-rw-rw- 1 user user 0 2011-01-29 02:04 read-write When I use sftp to put them in the destination machine I actually get: -rwxr-xr-x 1 user user 0 2011-01-29 02:04 execute -rw-r--r-- 1 user user 0 2011-01-29 02:04 read-write However when I set -u 0027 on sshd_config of the destination machine I actually get: -rwxr--r-- 1 user user 0 2011-01-29 02:04 execute -rw-r--r-- 1 user user 0 2011-01-29 02:04 read-write which is not expected, since it should actually be: -rwxr-x--- 1 user user 0 2011-01-29 02:04 execute -rw-r----- 1 user user 0 2011-01-29 02:04 read-write Anyone understands why this happens? scp - Independently of what is setup for sftp, permissions are always umask 0022. I currently have no idea how to alter this. ssh hostname - no problem here since the shell reads /etc/profile by default which means umask 0027 in the current setup. ssh hostname program - same situation as scp. In sum, setting umask on sftp alters the result but not as it should, ssh hostname works as expected reading /etc/profile and both scp and ssh hostname program seem to have umask 0022 hardcoded somewhere. Any insight on any of the above points is welcome. EDIT: I would like to avoid patches that require manually compiling openssh. The system is running Ubuntu Server 10.04.01 (lucid) LTS with openssh packages from maverick. Answer: As indicated by poige, using pam_umask did the trick. The exact changes were: Lines added to /etc/pam.d/sshd: # Setting UMASK for all ssh based connections (ssh, sftp, scp) session optional pam_umask.so umask=0027 Also, in order to affect all login shells regardless of if they source /etc/profile or not, the same lines were also added to /etc/pam.d/login. EDIT: After some of the comments I retested this issue. At least in Ubuntu (where I tested) it seems that if the user has a different umask set in their shell's init files (.bashrc, .zshrc,...), the PAM umask is ignored and the user defined umask used instead. Changes in /etc/profile did't affect the outcome unless the user explicitly sources those changes in the init files. It is unclear at this point if this behavior happens in all distros.

  • Making Active Directory changes atomic

    - by Matt Simmons
    I've got a Windows 2003 Active Directory infrastructure, and there are times (such as when terminating an employee) that I want instantaneous propagation across both of my AD servers. Currently, I make the change in both places, which I suspect is unhealthy, but it's the only way I know to make sure that the account is disabled to every machine. Is there a better way? Do I have to wait for the normal propagation time for convergence, or is there a way to "force" it?

  • Ubuntu not booting, recovery mode not loading

    - by TNC
    I have a dual-boot Ubuntu 11.10 and Windows 7 machine setup and last night I had to force shutdown Ubuntu during updates because it wasn't responding. Since then, Ubuntu will not boot up, only flashing a blank lit screen for a split second every couple of seconds. Booting in recovery mode does not help either, as it doesn't load at all. If anyone can help me diagnose what's wrong and figure out what to do, that would be greatly appreciated!

  • How long does a typical Windows 7 64bit installation take?

    - by Borek
    On a machine with Intel Core-i5 or i7 and a standard HDD, how long should an installation of Windows 7 64 bit roughly take? I'm after a rough estimate because my installation seems to be running quite slowly (previously, I've installed Win7 32bit on a laptop and it went much quicker but maybe there are differences between 32 and 64 bit editions).

    I have a machine with two harddrives. I have installed OpenSolaris on one of them and now I want to add the other one as a mirror-drive in my zpool rpool. I guess I have to format the second disk first and then add it to the pool. How can I do this?

  • Forcing IE8 Standards Mode with FEATURE_BROWSER_EMULATION

    - by earls
    I'm doing this: http://blogs.msdn.com/b/ie/archive/2009/03/10/more-ie8-extensibility-improvements.aspx But it's not working. I have "iexplore.exe" set to 8888 (decimal mode) under MACHINE, but it's still coming up documentMode = 5. I thought 8888 was suppose to force IE8 Standards Mode whether you have a doctype or not. What is going on?

  • Multi-core processors: Better performance running multiple applications?

    - by aip.cd.aish
    I realize for single applications - the application itself has to be designed to take advantage of multiple cores. But what about executing many different applications simultaneously? On my development machine at an average instance, I run multiple servers (a database server, a web server), multiple instance of IDEs (either Visual Studio or NetBeans), Web-browser with multiple tabs (in Chrome, each tab is a process on its own), FTP client, SSH client etc. Does having a multi-core system improve the ability to run multiple applications simultaneously?

  • Problems with Windows XP Plug and Play devices, maybe relating to MSVCR71.dll

    - by Richard
    I believe this question is unanswered as of now so I appologize if I've overlooked it. I have been having trouble some external devices with windows recently and I'm trying my darnedest to get to the bottom of it. At first, my Zero Tension USB mouse would stop working...as in the laser in the bottom of it would be on and would register movement, but the mouse on the screen wouldn't budge even an inch. At first this would happen randomly and then it would correct itself. As time went on, it became more and more frequent. At some point, the computer would make the "doo doo" sound of plugging or unplugging a USB device when the mouse stopped/started working. I dealt with it for a while and usually if I rebooted my machine, the mouse would work again for a day or two. As more time has gone on, the computer fully does not recognize the mouse AT ALL...I have another mouse that I use with the computer that works just fine and cannot seem to figure out why my Zero Tension mouse has failed. I tried plugging the Zero Tension mouse into my Mac and low and behold, it works without hesitation and never stops on me... Needless to say, I am stumped about this. I figured because I had another mouse I could deal with the loss of my fancy one for now...until my speakers stopped being recognized. I have a set of Logitec speakers that I have plugged into my sound card. Again, every now and again the audio devices would cease to be recognized by my computer, but a reboot would fix the problem. Now my speakers do not work at all with my computer and I feel like it's time to ask for help. My computer seems to be having a neural shutdown...where I can plug in devices and the computer doesn't seem to notice anything wrong, but none of the devices work. I hope this doesn't get any worse! Please help! Also, on a potentially (un)related note, when I start up my machine I get the message "This application has failed to start because Msvcp71.dll was not found. Re-installing the application may fix this problem." in reference to qbupdate.exe I don't know if that DLL being messed up has anything to do with my mouse or speakers, but I figure it might...anyway, thanks in advance for an answer and let me know if I need to clarify anything. Let me sum up: Zero Tension Mouse gradually stopped working Logitec Speakers gradually stopped working MSVCR71.dll seems to be messed up I don't know if any of those are related but any help would be much appreciated

  • OpenSolaris won't authenticate to OpenLDAP users with md5 passwords

    - by palmer
    I have an OpenSolaris machine here; I'm using it for the first time because I want to try out ZFS. ZFS itself is working great, but I cannot get opensolaris to authenticate against our openldap directory running on Linux with md5 or sha passwords; only crypt passwords work. I'd prefer not to have to use crypt passwords; is there some magic setting I'm missing that will enable md5 passwords to authenticate?

  • Cracking WEP with Aircrack and Kismet

    - by Jenny
    Just a minor question, but I notice with aircrack when it lists networks, it does not list the encryption type of each network. Which seems fair enough, as you can use Kismet, however on my machine when I end kismet and the server, the monitor interface is not removed and I cannot remove it manually, which screws with aircrack. SO, is kismet needed to view encryption types of networks, and if so how do you use it peacefully in unison with aircrack?
